Please register for full access to our existing data and tools. After filling out this form, you should receive your new username via email within TWO days.

  • If you submit the registration form but do not hear from us for TWO days, please contact us at crawdad AT If you submit the form and receive a blank page, please try removing any accents from your input. For some reason this sometimes causes the form to fail.
  • If you have forgotten your account name or password, please do not register for a new account; please use our password reset form.
  • Please do not share your CRAWDAD account; if a colleague wants to use the data as well, he or she should register for another account. Individual accounts allow us to contact you with news and updates, and help us to collect good statistics on the number of CRAWDAD users, their institutional types, and their home country. We never share individual data with others, we only collate statistical information.
  • Why is it important for us to collect this information? CRAWDAD operates on the generosity of several sponsors; by demonstrating the number and diversity of CRAWDAD users, we encourage them to continue their support.
